我生成了默认的设计视图:
rails generate devise:views
然后我username在views/devise/registrations/new.html.erb表单中添加了一个字段.
username
views/devise/registrations/new.html.erb
目前,仅email进行password验证.如何验证现场的存在性和唯一性username？我需要在User模型中添加一些东西吗？
email
password
User
validation ruby-on-rails devise
devise ×1
ruby-on-rails ×1
validation ×1
